Non-Perturbative Gluodynamics of High Energy Heavy-Ion Collisions

The dynamics of low-x partons in the transverse plane of a high-energy nuclear collision is classical, and therefore admits a fully non-perturbative numerical treatment. The authors report results of a recent study estimating the initial energy density in the central region of a collision. Preliminary estimates of the number of gluons per unit rapidity, and the initial transverse momentum distribution of gluons, are also provided.

WHAT IS NEW AT SMALL X*

The authors discuss some recent developments in small x physics. Current understanding of small x physics is that pQCD works at HERA and the Tevatron, but perhaps even better than expected. There is much flexibility in parton distributions to hide interesting new effects. Indeed, there are strong hints from HERA that one is on the threshold of a new regime of truly high parton densities, where one may expect qualitative changes in the behavior of distributions.
